It is shown that the injection of the filler to 10 mass % increases the impact strength compared to the original polypropylene. A further increase in the filler content to 20 % in the compositions reduces the impact strength to almost the value for the output polypropylene with an uncritical decrease in tensile strength. It is shown that the presence of 5 mass % of the modifier in the compositions increases the value of the relative elongation.It is determined that the developed composition with 5 mass % of the modifier and with varying the amount of filler can be used for the production of parts for cars for various purposes without significant changes in the technological cycle. The advantage of the investigated compositions is the reduction of energy consumption for the processing of highly filled compositions.

Interest to electrically conducting polymer composite materials in recent times has grown considerably, which is associated with the design of new branches of science and technology. The existing analogues are different in the complexity of production and high cost. One of the ways of solving the problem may be designing polymer composite materials with a combined filler. The research was carried out on creating electrically conducting hybrid polymer composites, based on emulsion polyvinyl chloride and polyethylene, using fillers of varying nature and dimensions. We studied the dependence of electrical conductivity of monoΒ and binaryΒfilled polymer composites on the type and content of fillers. It was found that the binary filling allows designing electrically conducting polymer composites, which are more promising economically compared to monoΒfilled ones. We defined physical and mechanical characteristics: tensile strength and relative elongation at break of obtained polymer composites. A method to improve them was proposed by introduction of a compatibilizer β graftΒpolymer of polyethylene with maleic anhydride.Depending on the value of the electrical conductivity, polymer hybrid composites can be used for: at a value of of elecrical conductivity 10β4β10β7Cm/cm as antiΒstatic materials; at 101β10β4Β Cm/cmΒ β as scattering antiΒstatic materials, at 101β 104 Cm/cm as currentΒconducting materials.Π Π°Π·ΡΠ°Π±ΠΎΡΠ°Π½Ρ ΡΠ»Π΅ΠΊΡΡΠΎΠΏΡΠΎΠ²ΠΎΠ΄ΡΡΠΈΠ΅ ΠΏΠΎΠ»ΠΈΠΌΠ΅ΡΠ½ΡΠ΅ Π³ΠΈΠ±ΡΠΈΠ΄Π½ΡΠ΅ ΠΊΠΎΠΌΠΏΠΎΠ·ΠΈΡΡ Π½Π° ΠΎΡΠ½ΠΎΠ²Π΅ ΡΠΌΡΠ»ΡΡΠΈΠΎΠ½Π½ΠΎΠ³ΠΎ ΠΏΠΎΠ»ΠΈΠ²ΠΈΠ½ΠΈΠ»Ρ

Sorption Properties of PET Copolyesters and New Approach for Foaming with Filament Extrusion Additive Manufacturing
The mass transfer process of binary esters of acetic acid in polyethylene terephthalate (PET), polyethylene terephthalate with a high degree of glycol modification (PETG), and glycol-modified polycyclohexanedimethylene terephthalate (PCTG) was studied. It was found that the desorption rate of the complex ether at the equilibrium point is significantly lower than the sorption rate. The difference between these rates depends on the type of polyester and temperature and allows the accumulation of ester in the volume of the polyester. For example, the stable content of acetic ester in PETG at 20 °C is 5 wt.%. The remaining ester, which has the properties of a physical blowing agent, was used in the filament extrusion additive manufacturing (AM) process. By varying the technological parameters of the AM process, foams of PETG with densities ranging from 150 to 1000 g/cm3 were produced. Unlike conventional polyester foams, the resulting foams are not brittle
New Approach for Extrusion Additive Manufacturing of Soft and Elastic Articles from Liquid-PVC-Based Consumable Materials
The article deals with the experimental development of a novel additive manufacturing (AM) process using a liquid consumable based on polyvinyl chloride plastisol. A conventional additive manufacturing system designed for deposition of melt filaments was converted to deposition of liquid material. Additive manufacturing with liquid plastisol enables the production of parts with low Shore A hardness and high ductility, surpassing the performance of the conventional filament process. The novel AM process enables the production of articles with a Shore A hardness of 5 to 60, and the mechanical properties of the additively manufactured articles are similar to those produced in the mold. This was achieved by varying the parameters of the AM process as well as the composition of the plastisol composition, including those filled with an inorganic filler. The application of different material distribution patterns also has a significant effect on the mechanical properties of the samples. A potential application of the investigated AM method was proposed and practically evaluated

Mechanical Properties of Flexible TPU-Based 3D Printed Lattice Structures: Role of Lattice Cut Direction and Architecture
This study addresses the mechanical behavior of lattice materials based on flexible thermoplastic polyurethane (TPU) with honeycomb and gyroid architecture fabricated by 3D printing. Tensile, compression, and three-point bending tests were chosen as mechanical testing methods. The honeycomb architecture was found to provide higher values of rigidity (by 30%), strength (by 25%), plasticity (by 18%), and energy absorption (by 42%) of the flexible TPU lattice compared to the gyroid architecture. The strain recovery is better in the case of gyroid architecture (residual strain of 46% vs. 31%). TPUs with honeycomb architecture are characterized by anisotropy of mechanical properties in tensile and three-point bending tests. The obtained results are explained by the peculiarities of the lattice structure at meso- and macroscopic level and by the role of the pore space
